Which device typically connects multiple networks?

The device that typically connects multiple networks is a router. A router is designed to route data between different networks, allowing them to communicate with each other. It operates at the network layer of the OSI model and makes decisions about the best path for data packets to travel based on their destination IP addresses.

While a switch connects multiple devices within a single local area network (LAN) and a hub connects devices but does so without filtering data, a router serves a different purpose by managing traffic between disparate networks, such as a home network and the internet. A modem, on the other hand, translates signals for transmission over the Internet but primarily connects to a single network. In summary, routers facilitate inter-network communication, making them essential for connecting multiple networks.
